Overview
Brief Summary
This study is designed to evaluate the safety and tolerability, pharmacokinetics and pharmacodynamics of single and multiple doses of ALXN2080 in healthy adult participants.
Detailed Description
Participants will be assigned to 10 different cohorts (6 SAD cohorts and 4 MAD cohorts), each with 8 participants on active treatment with ALXN2080 and 2 participants on placebo. ALXN2080 will be administered under fasted conditions throughout this study, except for the last SAD Cohort 6 in which ALXN2080 will be given with food to evaluate the effect of food on the single-dose pharmacokinetics of ALXN2080.
